From 84cd22c8cb722daaa9250a792da0f44930accfae Mon Sep 17 00:00:00 2001 From: Ryan Dwyer Date: Sat, 28 Jul 2018 22:13:13 +1000 Subject: Fix crash when a deferred command destroys a workspace Example config that produces the crash (with a single output): workspace 1 workspace 2 Prior to this commit, container_workspace_free would manually mark the L_FLOATING container as destroying and free it. This assumed the L_FLOATING container would never be involved in a transaction. This was a safe assumption when it was implemented, but became an incorrect assumption once parent/child relationships became transactionised. This commit removes the L_FLOATING free from container_workspace_free. When the workspace is destroyed, it starts the normal destroy process on the L_FLOATING container so it can be freed via transactions. --- sway/tree/container.c | 7 +++++-- 1 file changed, 5 insertions(+), 2 deletions(-) (limited to 'sway') diff --git a/sway/tree/container.c b/sway/tree/container.c index 6ebf2653..01387636 100644 --- a/sway/tree/container.c +++ b/sway/tree/container.c @@ -142,8 +142,6 @@ struct sway_container *container_create(enum sway_container_type type) { static void container_workspace_free(struct sway_workspace *ws) { list_foreach(ws->output_priority, free); list_free(ws->output_priority); - ws->floating->destroying = true; - container_free(ws->floating); free(ws); } @@ -196,6 +194,9 @@ void container_free(struct sway_container *cont) { free(cont); } +static struct sway_container *container_destroy_noreaping( + struct sway_container *con); + static struct sway_container *container_workspace_destroy( struct sway_container *workspace) { if (!sway_assert(workspace, "cannot destroy null workspace")) { @@ -240,6 +241,8 @@ static struct sway_container *container_workspace_destroy( } } + container_destroy_noreaping(workspace->sway_workspace->floating); + return output; } -- cgit v1.2.3
